Cool air from western Canada deposited in the Gulf of Alaska has created persistently stormy weather there. Though a storm is currently pounding the Pacific Northwest, models have trended weaker with any energy forecast to cross the Great Basin and affect the Steamboat Springs area for the weekend and next week. As a result, Friday will be dry with breezy west to southwest winds as the Pacific Northwest storm moves to our northwest.
Clouds will likely appear on Saturday with breezy conditions again as energy grazes our area, with showers confined to the very northwestern corner of Colorado.
Similar conditions are advertised for Sunday with less cloudiness likely.
Monday should start dry, but some energy from the Pacific makes it close enough to our area to bring a cool front through the area later in the day , threatening showers for the afternoon and into the evening.
Tuesday looks to be dry before another pulse of Pacific energy brings another mostly dry cool front through the area on Wednesday.
Models advertise the Gulf of Alaska storm elongating southward along the West Coast next week, pumping up a ridge of high pressure over the Intermountain West that should create beautiful and warm weather for the end of the work week and heading into the weekend.

The sharp and unstable ridge along the Canadian coast has materialized as advertised in the last forecast, forcing cool air from western Canada southward into the Pacific Northwest. Additionally, some Pacific energy will undercut the ridge and allow several shallow waves to moves across the area and threaten rain showers as soon as late this afternoon and overnight.
Increasing moisture and instability ahead of the advancing Pacific Northwest storm and additional disturbances undercutting the ridge brings a good chance of rain showers to the Steamboat Springs area on Tuesday, especially later in the day, with high snow levels.
Wednesday is forecast to be cooler and dry before another Pacific wave undercuts the rapidly disappearing ridge off the Canadian coast. Models have trended weaker and further south with the undercutting energy likely keeping showers to our south on Thursday.
While Friday currently looks dry and breezy, the breakdown of that unstable ridge allows more substantial Pacific energy to impinge on the West Coast and cool western Canadian air to pour into the Gulf of Alaska, ushering in a likely long-lasting and more active weather regime for the West. Models are now more aggressive in bringing another relatively warm wave across our area early in the weekend, with some forecasting breezy conditions and showers with high snow levels on Saturday.
Sunday looks to be an in-between day before a much colder and stronger wave threatens precipitation with snow levels approaching the valley bottom early in the next work week.

Temperatures are rebounding nicely in Steamboat Springs today after a chilly start under clear skies behind the departing storm system. After another chilly start Saturday morning, temperatures will continue to warm through the weekend as a flat ridge moves over the area.
A weak wave moving south of us from the southwestern U.S. may bring some clouds to the area on Sunday, but any precipitation should be confined to southern Colorado.
By Monday, a wave from western Canada will move southward along a sharp and unstable ridge along the Canadian coast and phase with some Pacific energy undercutting the ridge and moving across the desert southwest. Though the cool air from Canada looks to affect mainly the Front Range on Tuesday, increasing moisture and instability ahead of these disturbances brings a chance of precipitation to Steamboat Springs later Monday and especially through Tuesday with likely high snow levels.
At this point, Wednesday is forecast to be dry before more substantial Pacific energy undercuts the rapidly disappearing ridge off the Canadian coast. Though models have trended weaker with the undercutting energy traveling over our area by Thursday, there may still be a chance of showers with high snow levels.
Interestingly, the breakdown of that unstable ridge also allows cool air from western Canada to move westward into the Gulf of Alaska by late in the work week, pumping up a temporary ridge over the Intermountain West and advertising another beautiful weekend. The storm that develops in the Gulf of Alaska over that weekend my affect our weather the following work week.

A Pacific storm that has crossed the West Coast this morning will race across the Great Basin tonight. The storm has evolved considerably since Thursday’s forecast with the storm now forecast to be comprised of two distinct pieces. The first part of the storm is about a day faster and drier, bringing a cool front through the Steamboat Springs area during the day Monday. Breezy southwest flow will veer to the west and northwest when the front passes with a band of showers moving through around noon or early afternoon.
The brunt of the storm will be deflected to our north by a ridge of high pressure over the central US. with some drying advertised over our area behind the front later Monday into Tuesday. Despite the drier weather, temperatures will be cool on Tuesday as additional energy from the northwest keeps cool air flowing into the region.
Multiple waves of additional energy will keep temperatures cool and eventually moisten the atmosphere, bringing showers back into our area for Wednesday. It will be cold enough for snow on Mt. Werner, and we may see some snowflakes in the valley around Wednesday afternoon or evening.
The waves of energy continue for Thursday and into the overnight, with continued snow on Mt. Werner and snow showers likely in the valley. While accumulations on the still-warm paved surfaces are unlikely, there may be some accumulations on the grassy areas.
Warming and drying is advertised to start Friday after a chilly start to the day and last through the weekend behind the the last wave that is forecast to cross the area Thursday night.
For those that plan travel to the East Coast over Columbus Day weekend, be aware that long range models have a hurricane threatening the East Coast. There is still lots of uncertainty, though, as not only may the track of the hurricane change, but it may or may not interact with the second part of our forecast storm as it moves eastward.
